Viris doctis, qui vel consilio, vel libris suppedi tandis me knevole adjuvarunt, et privatim me de vinctum ostendi et publice hoc loco grates 'quam maximas persolvo; nec magis silentio premere velim redemtoris voluntatem, qui nihil antiquius ?abuit, quam ut haecoe'editio quam nitidissime prodiret in publicum. Die quid esset, quo nostra careret editio, in Addendis paucissima quaedam adjeci, quae notatu digna reperi in editione quadam Ctesìae, quae meis omnibus dhartis jam ad typothetas transmissis, nuper admodum prodiit.
Ctesias was a Greek physician and historian from Cnidus in Caria. Ctesias, who lived in the 5th century BC, was physician to Artaxerxes Mnemon, whom he accompanied in 401 BC on his expedition against his brother Cyrus the Younger. Ctesias was the author of treatises on rivers, and on the Persian revenues, of an account of India entitled Indica (which is of value as recording the beliefs of the Persians about India), and of a history of Assyria and Persia in 23 books, called Persica, written in opposition to Herodotus in the Ionic dialect, and professedly founded on the Persian royal archives.
